To all'whom it may concern:

Be it known that I, JAMES M. BOYLE, a citizen of the United States, and resident of the city, county, and State of New York, have invented certain new and useful Improvements in Comparative Recording Apparatus, of which the following is a spec1iication, taken in connection with the accompanying drawings, forming part of the same.

This invention relates to comparative recording apparatus for recording the weight or other properties of articles at successive periods of a manufacturing or treating process. Testingr devices are arranged at suitable stations so that they act upon each one of the series of treated articles at that stage of the process. determining their weight, temperature, electrical conductivity, or other properties. These testing devices are connected with a multiple recorder com rising a series of indicators, each one of W 'ch is connected with and actuated by the corresponding testing device and the record in the form of a strip or otherwise is fed through the recorder in such way that the several indications relating to a single article may be grouped together for ready comparison.

The illustrative embodiment of this invention relates especially to apparatus for recording the weights of ties or similar articles at successive stages of a timber preserving process to which they are subjected.

In the accompan ing drawings diagrammatically showing ilustrative embodiments of this invention, Figure 1 is a longitudinal sectional View. Fig. 2 is a transverse sec# tion. Fig. 3 shows diagrammatically the circuit connections. Fig. 4 is a vertical section on an enlarged scale through the indicator. Fig. 5 shows a portion of the record strip.

In the illustrative embodiment of this invention shown in the drawings, a series of timber preserving tanks are indicated. The hot oil tank 8 may contain the hot creosote or similar material kept at the desired temperature by steam pipes or other heatingydevices.A The sprocket shafts 21, 25 may as indicated be journaled transversely adjacent either end of the tank to support and operate the sprocket or feeding chains 23 provided with the grippers 24 at intervals along the same. These grippers are adapted to engage tle valve 16, and the stem of the hoist 4 may the projecting ends of the shaft secured to the tie bundle 17 or other article to be treated so as to feed the article slowly through the tank. This shaft may be provided as indicated in Fig. 2, with the guide wheels 18 to engage the guides 40 arranged on the sides of the tank so that the article 17 lowered into the tank at its receiving end is engaged by the grippers, carried under the surface 26 of the creosote or other treating material and then carried slowl along the tank in the position of the artic e 22 shown in Figs. 1 and 2. The cold oil tank 9 may be provided with similar sprocket shafts 28, 30 actuatin the feed chain 29 in similar manner to fee articles through the cold creosote or other material 27. The solution tank 10 for containing the zinc chlorid or other antiseptic solution may be located in the same line as the other tanks 8 and 9 and carries similar sprocket shafts 31 to operate the feeding chain 33 having the grippers 32 thereon.

For the convenient insertion and transfer of articles through these tanks, suitable hoists 4, 5, 6 and 7 may be provided at stations at the initial end of these tanks and at the discharge end of the solution tank, these hoists being shown as supported by suspenders 11 from the sup orts 1, 2 and 3. Standard air hoists may e used for this pur ose, actuated in the usual way through the tlirotbe secured to the balance or spring scale 12 from which the hook 39 is supported, so that articles hanging on this hook and lowered by the hoist into the hot oil tank 8 can be conveniently weighed at such time by the balance 12. ln this particular treating process the articles arranged on the table '20 are picked up after being arranged in suitable units, if desired, and lowered into the hot oil tank 8 by the hoist 4 after bein weighed at this initial station. Then after eing slowly fed through the hot oil'tank the articles float or are raised to the top of the oil at the discharge end of the tank and may then be quickly raised upon the hook 38 by the operator using the air hoist 5 at the second station and weighed at this stage of the process before being lowered into the cold oil tank 9 which should be done as quickly as possible. Each article after passing through the tank 9 floats or is raised to the surface of the liquid in the same way and may be raised by the hoisgt at the third station and weighed beforedbeing lunged into the solution tank 10. At the disc ar e end of this tank the article may be raised the hoist 7 at the terminal station and weig e d at the end of the treating process before being placed o n the car or other receptacle 35.

Each of the balances may be provided with the balance bar 87 meshing, as indicated in Fig. 3 with the balance pinion 86 so as to rotate the balance arm 45 when pulled down against the weighing spring as customary in such balances. The arm 45 passes over and makes electrical contact with the balance coil or resistance 59 which may be arranged circumferentially on the balance as indicated. A currenty of the desired strength may be sent through the balance coil by the battery or other source of electricity 79, the circuit eX- tending through the re ulator resistance 81 which may be adjusted y the movable contact 80, as indicated, the potential of the circuit being ad'usted from time to time in accordance wit the indications of the regulator or volt meter 78. In this way the balance arm makes electrical contact with different parts of this balance coil as the arm moves around its scale and an electrical current of corresponding intensitypasses through the indicator circuit 82 so as to actuate tlie needle 91 of the indicator 63 to the proper extent. This indicator may be any electricalindicating apparatus, such as a standard volt meter moving the needle substantially in proportion to the potential of the point engaged by the balance arm, the absolute position of the needle being adjustable by regulating the amount of resistance in the resistance coil adjacent the balance which is in the indicator circuit, so that zero settings can be conveniently made at any time. As indicated in Fig. 4, the needle 91 may swing about its pivot 71 within the case of the instrument and carryat its outer free end the marker 92 which in this instance plays in a circular arc over the impression strip 69 and the record strip 68 and normally out of contact with such strips, the position of the marker upon the record strips thus indicating the weight of the article suspended from the hook 39.

Under thedescribed conditions of use the hoists are only intermittently employed in lifting articles and the o erator at each station may raise an artic e by the hoist and then when the balance has ceased to oscillate so that it correctly indicates the weight of the article, he may produce a suitable mark on the record strip b operating suitable actuating means whic may co'mprise the actuator switch 49, which may be in the form of a push-button or the like. This closes the actuator circuit, allowing electricity from the battery or other source of.

potential 54 to flow through the line 53, the switch 49 aiidline 55 to energize the actuator magnet 67 and the feed magnet 64. When the actuator magnet 67 is energized the armature on the actuator 70 is attracted and swings down, making forcible contact with the marker 92 and causing the proper mark or impression to be made on the record strip,

after which the circular actuator is drawn upward by the spring 72 into inactive position in the illustrative construction indicated. The closing of the actuator switch may also serve to feed forward the record strip one space after the marker has made its record; and any desired form of electrical esca ement may be used for this purpose, a diiagrammatic arrangement being indicated in l1`ig.4 as comprising the feed magnet 64 operating to draw the feed lever 85 forward against the action of the spring 84 so that the pivoted spring-pressed arm 83 acts u on the ratchet 74 on the feeder 73. his ratchet as indicated may also serve to engage the holes 77 which are indicated in Fig. 5 as being formed along the edges of the record strip so that the strip is positively fed forward to the desired extent.

As indicated, the multi le recorder may comprise in this instance our similar indicators 60, 61, 62 and 63, connected 'to and actuated by the balances and actuator vswitches at the various stations to act successively upon the record strip 68 fed through them by the intermittently actuated feed roll 73 in each indicator. 1n order to make certain that the successive marks made by eacho indicator are located at the proper point along the strip, take-ups may e arranged between the indicators of the series, as shown in Fig. 4. The take-up roll 76 is indicated as guided in suitable rooves located between the feeder 73 and t e next idle roll 75 over which the strip 68 passes so that a loop of the desired length may be made in the record strip. With this arrangement it is unnecessary that the various weighing operations be exactly timed and the articles may be weighed at the various stations at any time desired so long as they are kept in the pro er order as they are weighed and passed t rough the various steps of the treatmg process. In this particular timber preserving process the articles fed into the hot oil tank contain some moisture which is driven off by the heat of the oil in this tank s o that the initial weight A of an article, that is the weight indication given by the weight mark A made on the record strip by the marker of the first indicator of the series, is greater than the weightB shown in Fig. 5 when the article leaves the hot oil tank at the second station. The articles absorb some creosote'in the cold oil tank so that the weight C of the articles at the third station when they have left this tank is greater than v any one article may be brought into proper alinement 'so that the Weig ts of a single article may if desiredbe located on the same circular arc 100, as shown in Fig. 5, an'd the weight indications on the arc 101 Valso relate to another article; and under these conditions this would necessarily remain the case so long as the articles were maintained in the same order throu hout the various stepsof the process., In t is way a very convenient com arison of the effect of such a treatment on tlie different articles may be made; the amount of absorption of the various preservatives being directly indicated in a very graphic way as well as the amount of moisture driven oil during the preliminary stage of the process, it being understood, however, that the indications shown in Fig. 5 are diagrammatic only and do not correspond exactly to numerical results obtained in this treating process.
